- The present invention relates to a telecommunications system and more particularly to a telecommunications system that includes a number of subscriber apparatuses, a number of telephone exchange units and a number of mobile subscriber apparatuses. as stated in the preamble of
claim 1. - Thus, the invention is based on a system with which a call incoming from a chosen permanent subscriber apparatus belonging to the system or from a mobile subscriber apparatus also belonging to the system can be connected to a chosen permanent subscriber apparatus or to a mobile subscriber apparatus with the aid of a telephone exchange unit or telephone switching unit, which preferably includes associated computer equipment.
- It is also required by the present invention that the telecommunications system has a so-called A-number identification means, wherein each call is accompanied with information concerning the identity of the caller, such as telephone number, therewith enabling the telephone exchange unit and/or the computer equipment to evaluate the geographical area and/or position of the calling subscriber apparatus after each received call, on the basis of this identification.
- It is also required by the present invention that the telephone exchange unit and/or the computer equipment included in the telecommunications system is/are able to evaluate and has/have evaluated, established and stored the geographical areas and/or positions applicable to each of a number of available, i.e. callable, mobile subscriber apparatus.
- A special Private Branch Exchange (PBX) may include a so-called "call transfer function", meaning that a call which is received in a PBX on a first input terminal and which, subsequent to evaluation, shall be connected to one of said evaluated, available mobile subscriber apparatus, shall initially be received by a telephone operator or in unattended telephone exchanges or switching centres, to be connectable to a device for connection to a speech generator that includes means for generating and presenting instructions and/or questions to the calling subscriber and, subsequent to evaluating which mobile subscriber apparatus shall be indicated or pointed out, activates means associated with said PBX such as to call the indicated mobile subscriber apparatus, whereafter the telephone operator or said means is released from the connection setup through the PBX.
- There are used in the following description such expressions as "permanent system-associated subscriber apparatus". This category of subscriber apparatus does not only include such subscriber apparatus that can be connected to a telephone exchange unit or PBX through a physical telephone line, but also includes other telephone apparatus. However, it is essential to the invention that the telephone apparatus and/or the geographical area of calling person, preferably the geographical location of said person, can be established unequivocally.
- Also used in the following description is the expression "mobile system-associated subscriber apparatus", by which is meant subscriber apparatus that is allocated to a mobile unit, for instance a taxi cab, express delivery vehicle, mobility service vehicles and like vehicles equipped with a mobile telephone equipment, and where it is possible to establish clearly the geographical area and/or the exact location of the unit at any moment in time.
- The subscriber apparatus may be a "permanently" connected apparatus. By a permanent subscriber apparatus is meant, in addition to the accepted meaning of the term, a mobile subscriber apparatus which has informed the exchange unit PBX or switchboard that calls will be received at a particular location, the subscriber apparatus of a taxi rank or like station.
- Technicians familiar with this field, however, will be aware of the types of subscriber apparatus that can be used.
- It is also indicated in the description that the "subscriber apparatus" is active or activated by calling and leaving messages, although it will be understood that each such activation is initiated and effected either automatically or by a person serving the subscriber apparatus concerned.
- It will also be understood that the terms "telephone exchange" and "telephone exchange unit" do not refer only to a telephone exchange or a telephone station or a switching centre, but also to Private Branch Exchanges, switchboards, private manual branch exchanges and so on.
- Although the present invention can be expected to obtain particular application in respect of so-called "taxi telephone exchanges", i.e. a particular telephone exchange unit or PBX that is adapted for taxi vehicles where a telephone operator is able to receive calls and provides information regarding the transportation needs of a customer, etc., and where each customer is able to call one single telephone number coordinated for a group of taxi cabs, suitably an easily memorized telephone number, it will be understood that the present invention can also be applied to other telephone exchange units and for other purposes.
- With regard to the significant features of the present invention and other features relating thereto, it can be mentioned that there are known to the art different types of telephone exchange units and/or PBX which fulfil the aforesaid basic requirements regarding the function of the present invention.
- The call transfer function is known to the art and is included in many telephone exchange units and PBX, such as operator-manned subscriber exchange units.
- The AXE subscriber switching network, retailed by Ericsson, Stockholm, Sweden, under the designation "AXE-station" is one example of a telephone exchange unit that incorporates a "call transfer function" or facility.
- With regard to the present state of techniques, particular reference can be made to the teachings of U.S. Patent 5,432,840, in which there is described and illustrated a method and an arrangement for selective connection of a permanent subscriber apparatus to a nearby mobile subscriber apparatus with the aid of exchange switching functions.
- The reader is referred to this U.S. patent publication for a more basic understanding of the present invention and related known techniques.
- It is also known to the prior art means adapted to establish or evaluate the geographical area and/or the location of a calling subscriber apparatus.
- In this respect it is possible to use the A number identification for indicating the area or location.
- It is also known to use a register where a A-number identification is coordinated with a relevant location.
- It is also known to ask the caller of its location.
- It is also known to use memory means for storing therein at least the geographical areas and/or the locations that apply for each of a number of available mobile subscribe apparatus by using available navigation systems, as a GPS-system.
- When considering the state of the prior art, as described above, it will be seen that a technical problem, with in telecommunications systems of the kind described in the introduction, and where the geographical locations of a mobile subscriber apparatus are structured within defined geographical areas, resides in the provision of conditions such that a mobile subscriber apparatus automatically can indicate via a telephone call when it leaves a delimited geographical area and enters into an other delimited geographical area, an adjacent geographical area.
- There is also a technical problem in realizing the advantages that are obtained as the automatic indication is limited to such mobile subscriber apparatus that are stationed in cars, available for an immediate assignment.
- It is also a technical problem to, with simple means and measures, be able to provide conditions such that selected delimited geographical areas are given well adapted and suitable borders.
- It also ought to be regarded as a technical problem in realizing the advantages of representing each delimited area with its area significant telephone number.
- It is also a technical problem in realizing the conditions required in order to, in a mobile subscriber apparatus be able to establish through a navigation system, and, at a transition from one delimited geographical area to an other delimited geographical area, automatically be able to initiate a call to a telephone exchange, unit a PBX or the like, in order to, within it, register the identity of the queue-order and the present area of the calling subscriber apparatus.
- Another technical problem is one of realizing the significance and the simplicity of allowing said indication from a mobile subscriber apparatus to take place over a standard telephone connection, having the form of a "short call" that requires no answer, and preferably while using the A-number identification, which by said call can be registered within the telephone exchange unit or PBX or the like.
- It will also be seen that a technical problem is one of realizing the significance of and the advantages that are afforded by allowing each mobile subscriber apparatus to automatically initiate a call to the telephone exchange unit or PBX and thereby achieve a call setup through the telecommunications system to said telephone exchange unit or PBX, said call setup being chargeable or not chargeable to the mobile subscriber apparatus.
- With the intention of solving one or more of the aforesaid technical problems, the present invention is based upon a telecommunications system, which includes a number of subscriber apparatus, a number of telephone exchange units, and a number of mobile subscriber apparatus, in accordance with the definition given in the preamble of
claim 1. - It is proposed that, in a telecommunications system of this kind, each mobile subscriber apparatus, belonging to the system, is provided with, or connected to, a navigation system for the establishing or evaluation of the momentary geographical location of the subscriber apparatus, and further features as stated in the characterizing part of
claim 1. - Proposed embodiments, falling within the inventive thought, are stated in the subclaims.
- The primary advantages that are afforded in a telecommunications system, in accordance with the present invention, reside in the provision of conditions for an automatic indication of the momentary geographical locations or areas of available mobile subscriber apparatus. Respective available mobile subscriber apparatus may automatically make an entry of its position and present area, through the activation of a call to an area significant telephone number, or the like,
- An embodiment of a telecommunications system at present preferred and having features significant to the present invention will now be described with reference to the accompanying drawings, in which;
- Figure 1
- is a schematic overview of an inventive arrangement which, for the sake of clarity, is shown to include only one permanent subscriber apparatus and only one mobile subscriber apparatus;
- Figure 2
- is a simplified block schematic of a proposed equipment within a mobile subscriber apparatus; and
- Figure 3
- is a simplified block schematic of a proposed equipment within an equipment belonging to a telephone exchange unit or a PBX.
- Figure 1 illustrates a telecommunications system "S" which is constructed in accordance with the principles of the invention and which includes a telephone exchange unit, in the form of a
telephone station 1, provided with the necessary selector devices 1a, 1b for connecting each incoming call to a subscriber, directly or indirectly, chosen by the calling subscriber. - The illustrated embodiment includes the particular case in which each call to a chosen "group number" shall be handled by a special computer apparatus, without the aid of a telephone operator.
- The telephone exchange unit or
PBX 1 includes acontrol equipment 2 and computer equipment and/orsystem 3 connected to the control equipment by conductors, wherein thecontrol equipment 2 and thecomputer system 3 coact mutually to activate and execute a chosen through-connection function. This through-connection function is designated "transfer" and is known as an integrated function in telephone stations and telephone exchange units, switching centres, and consequently it is unnecessary to describe this activation and implementation of the transfer function in detail in this document. The invention is based on such activation taking place through the medium of thecomputer equipment 3. - It suffices to establish in this regard that a call incoming from a person having a
permanent subscriber apparatus 5 via a group number and through the medium of coaction with equipment in the telephone exchange is, inter alia, able to influence the transfer function and is connected directly to amobile subscriber apparatus 8, being a part of ataxi cab 9 or the like, selected by thecomputer equipment 3 through the medium of special criteria. - The
telephone exchange unit 1 can be called by a number of permanent system-associated subscriber apparatus, with the aid of a number ofphysical lines 4 belonging to group numbers, of which apparatus only one is shown in Figure 1 and referenced bynumeral 5. - Extending from the
telephone exchange unit 1 is a number of out-going lines 6, of which one with number 6a, is connected to anequipment 7, with whose aid a speech connection can be established with a mobile system-associated subscriber apparatus chosen from among several available apparatus, wherein only one such apparatus is shown. This apparatus is referenced 8 in the drawing. - When the
subscriber apparatus 5 has activated a "group number", the call will be through-connected to a chosenoutgoing line 6b, to which acomputer equipment 10 is connected. - It is assumed that the mobile system-associated
subscriber apparatus 8 is mounted in ataxi cab 9, and that theapparatus 8 is manned by a cab driver. - The transfer of a telephone call form the
unit 7 to thesubscriber apparatus 8 can be effected in a known manner, for instance with the aid of the mobile telephone system, designated NMT900/450, that has been in use in Sweden for many years. The telephone exchange unit may include equipment, such as saidcomputer equipment 10, or may be connected to an external equipment, such as computer equipment, through the medium of one ormore conductors 6b, as illustrated in Figure 1. - The arrangement illustrated in Figure 1 also includes a queue-
organizer 11 that functions to place in a queuing order calls incoming from a number of permanent, simultaneously calling ,subscriber apparatus 5. - The following description is based on the occurrence of only one call, and consequently the function of the queue-
organizer 11 need not be described in detail. - A
stationary subscriber apparatus 5 can be connected selectively to anearby subscriber apparatus 8 chosen by the computer equipment, with the aid of said telephone exchange unit and saidcomputer equipment 10 coacting therewith, even when thepermanent subscriber apparatus 5 activates a call to a given group number. - In order for this to be possible, it is necessary for a
telephone exchange 1 to connect all incoming calls directed to said given group number to thecomputer equipment 10, which includes devices and means which, subsequent to establishing a call connection between thepermanent subscriber apparatus 5 and thecomputer equipment 10, function to generate artificial speech and compile questions and, in accordance with the answers given, establish the geographical area and/or the place in which thepermanent subscriber apparatus 5 is located. - This can be achieved by requesting the
permanent subscriber apparatus 5 to key-in the first two digits of its own telephone number, for instance through the medium of its keypad 5a, said code being able to establish the geographical area in which the subscriber apparatus is located through the medium of means (not shown) connected to a device (not shown). - Alternatively, the
permanent subscriber apparatus 5 may be requested to key-in the post code or zip code of the geographical area concerned, through his keypad 5a. - According to one variant, which is most preferred, the
telephone exchange 1 is able to evaluate the number (A-number identification) of the callingsubscriber apparatus 5 in coaction with thecomputer equipment 10, and to establish the location and also the address of the subscriber apparatus through the medium of saidcomputer equipment 10. - The present invention is thus based on the ability to evaluate the location and the address of the subscriber apparatus, and also on the ability of establishing the locations and possible addresses of every available subscriber apparatus and storing this information in the telephone exchange unit, and on the ability of the telephone exchange unit to transfer the call of a calling
subscriber apparatus 5 to a selected nearby available calledsubscriber apparatus 8. - Reference is made to the aforementioned American patent application for a clearer understanding of suitable switching arrangements in this respect, and then particularly to the embodiment described with reference to and illustrated in Figure 3.
- With reference to Figure 2, there is shown in a simplified manner a block schematic of the equipment required in the
mobile unit 9 orsubscriber apparatus 8. - The
mobile unit 9 comprises anavigation system 20 of a previously known kind, and the momentary position in a coordinate system of the geographical location of the mobile subscriber apparatus is evaluated or established through thissystem 20. The coordinates of the position can be regarded as appearing online 20a. - A
memory 21 holds an information of the geographical positions or coordinates that are given to one and the same area. The geographical positions of several delimited areas are also stored in this memory. - A delimited area ought to be given suitable geographical borders. One such suitable border can be the one that coincide with the borders of a post code area.
- The
memory 21 can preferably include very narrow delimited areas for the centre areas of a town, narrow delimited areas for the suburban areas of a town, and large delimited areas for the more out of town areas. - The embodiment is limited to schematically presenting
certain areas - First means 41 are adapted to be able to compare the momentary position (appearing on
line 20a) of themobile subscriber apparatus 9 with the geographical positions already stored in thememory 21. - Said first means 41 can also comprise a memory where a previous position of the
unit 9 is stored or where a code belonging to an area is stored. - The
unit 9 is supposedly within thearea 21a. - At a comparison by said first means 41 that gives a position within a different geographical area, for
instance 21b, than that of an immediately previous comparison (21a), second means 42 are adapted to activate third means 43 in order to initiate and perform a call to thetelephone exchange unit 1, which registers and stores a performed area transition. - It should be noted that said third means 43 can only be activated when the
unit 9 is available for an assignment. - Available or idle marks are generated in fourth means 44, that can be connected to a fare meter, or the like.
- Figure 2 shows a contact, labelled 44a, which is put into a closed state at an available mark and an open state at an idle mark.
- The third means 43 also comprises a
memory 43a, wherein a number of telephone numbers are stored, one for eacharea - The telephone number that corresponds to the
present area 21a is firstly evaluated, whereafter a connection is made to thetelephone exchange unit 1, as themeans 43 receives signals to initiate a call to that telephone exchange unit. - The selected telephone number directs the connection through the communications network to an
input connection 45 of thetelephone exchange unit 1, which input connection has been given a number. - The
telephone exchange unit 1 receives said call in acircuit 31, according to Figure 3, and the received A-number identification is stored within a position "A" in amemory 32, but theexchange unit 1 leaves no answering indication. - The
memory 32 can be regarded as representing every available taxi cab within thearea 21a, in queue-order and with the A-number identifications "A", "B" and "C". - An
other area 21b has its own telephone number, directed to another connection 46, which in a similar manner is stored within a memory 32' and where available taxi cabs within thearea 21b are represented in queue-order "D", "E", "F", and so on. - A
circuit 33, connected to thememories 32, 32', is adapted to control the content of thememories 32, 32', and thecircuit 33 is adapted to remove an available taxi cab (A) incoming to thearea 21b from an other area (21a) as soon as the registration (A) has been performed within the own area (21b). - It is also fundamental to the invention that this call shall only need to load the
telephone exchange unit 1 with low costs or with no cost at all, since the costs involved through the telephone exchange unit must all be distributed equally between the system subscribers. This would seem to be the only practical possibility, irrespective of whether an individual subscriber utilizes the system or not. - In this regard, it is proposed in accordance with the invention that although the
subscriber apparatus 8 makes a call to thetelephone exchange unit 1, the means 43 (Figure 2) will be adapted so that when the connection is established and the A-number identification has been sent to thememory 32, 32' of the telephone exchange, this will represent an "indication" of thatsubscriber 8 has now been transferred to an other area. - So that this "indication" can be made without cost to the
telephone exchange unit 1, it is proposed that a call established over the available telephone system shall only be noted by thetelephone exchange unit 1 and without answering or needing to answer the call. - This can be done by letting the
subscriber apparatus 8, through thecircuit 43, terminate the connection before thetelephone exchange unit 1 has answered the call, or by adapting the circuits in the telephone exchange unit to not answer calls. - Alternatively, the call can be made over a communications path separate from the telephone connection and having the form of a data connection, or the like.
- According to the present invention, at least some of the
available subscriber apparatus 8 are coordinated with respect to category in a memory of thetelephone exchange unit 1. This is shown in Figure 3 with a memory (32) in dotted lines. - Each of the available mobile subscriber apparatus is adapted to insert into the computer equipment an available mark and a code that reveals its immediate geographical area or geographical location, through its own connection with the telephone exchange unit.
- Subsequent to establishing a connection, each mobile subscriber apparatus will be allocated a category and a queue order in the
memory 32, (32), 32' within the telephone exchange unit. The category can be evaluated from the A-number identification. - The
telephone exchange unit 1 and/or thecomputer equipment 10 may conveniently utilize means for, inter alia, generating artificial speech, which presents certain instructions and questions to the calling subscriber and stores his/her messages and answers. - The separate communications channel may be a data link, such as a Short Message Service, SMS, or a person-paging system that includes written messages, or alternative the mobile GSM system.
- It will be understood that the invention is not restricted to the aforedescribed and illustrated exemplifying embodiment thereof and that modifications can be made within the scope of the inventive concept as defined in the following Claims.
